A Deep-To-Shallow Transition In The Fort Payne Formation (Lower Mississippian), Kentucky Highway 61, Cumberland County, Kentucky, David L. Meyer, Paul E. Potter, Jennifer L. Thies, William I. Ausich, Stephen A. Leslie

Map and Chart--KGS

The Fort Payne Formation of the Cumberland Saddle region of south-central Kentucky and north-central Tennessee is part of a vast marine sedimentation system that extended over much of North America during the Early Mississippian Period; broadly similar facies reached from Georgia through Tennessee and Kentucky, into western Illinois and Missouri, and into New Mexico and the northern Rockies (Pryor and Sable, 1974). Throughout North America the Fort Payne and its equivalents overlie a black shale (in Kentucky called the Chattanooga Shale) and underlie thick carbonates (in Kentucky, the Warsaw Formation and younger middle Mississippian limestones).

Profitability Of Variable Rate Fertilization On A Kentucky Soil (A Theoretical Analysis), Lloyd W. Murdock, Paula L. Howe

Soil Science News and Views

Grid soil sampling and variable rate fertilizer applications are a part of the precision agriculture movement that has captured the interest of many farmers. Variable rate fertilization requires extra expense and effort plus the use of often unfamiliar technology. Global Positioning Systems (GPS) equipment and computer software are used to outline and grid the field into small manageable units or “cells” (usually 2.5 acres). Each grid cell is soil sampled and tested for pH and available nutrients. Fertilizer recommendations are made on each grid cell and the fertilizer is spread by each grid cell using a truck equipped with GPS …

Western Australia Soil Acidity Research And Development Update 1997 : Time To Lime, Department Of Agriculture And Food, Western Australia

Bulletins 4000 -

There is a lot of lime being spread in Western Australia – or is there?

In fact, the Australian Bureau of Statistics agricultural census paints a picture showing that we are still far short of the amount of lime that should be getting on to the ground.

For many years Western Australian soils acidified without significant production penalties. The soil pH was at values that were not affecting plant growth. However, over the last decade or so, large areas of soils have reached the point where production is being affected. In addition, we are now introducing plant species such as …

Comparison Of The Projector Augmented-Wave, Pseudopotential, And Linearized Augmented-Plane-Wave Formalisms For Density-Functional Calculations Of Solids, N. A. W. Holzwarth, G. E. Matthews, Rodney Dunning, A. R. Tackett, Y. Zeng

Chemistry & Physics Faculty Publications

The projector augmented-wave (PAW) method was developed by Blöchl as a method to accurately and efficiently calculate the electronic structure of materials within the framework of density-functional theory. It contains the numerical advantages of pseudopotential calculations while retaining the physics of all-electron calculations, including the correct nodal behavior of the valence-electron wave functions and the ability to include upper core states in addition to valence states in the self-consistent iterations. It uses many of the same ideas developed by Vanderbilt in his "soft pseudopotential'' formalism and in earlier work by Blöchl in his "generalized separable potentials,'' and has been successfully …

Detecting Fire And Grazing Patterns In Tallgrass Prairie Using Spectral Mixture Analysis, Carol A. Wessman, C Ann Bateson, Tracy Benning

Environmental Science

Global grasslands are typically under management practices (such as fire and grazing) that alter nutrient cycling, ecosystem composition, and distribution of organic matter from the unmanaged condition. We evaluated landscape-level response to fire and grazing treatments in the Konza Tallgrass Prairie Research Natural Area, Kansas, using spectral mixture analysis of Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data acquired 31 August 1990. Spectral mixture analysis derives the fractional abundances of spectrally unique components in the landscape. The reflectance spectra of these components are called endmembers. Endmember fractions values were compared against ground values of live biomass, current standing dead biomass, and litter …

Identification Of The Adp-L-Glycero-D-Manno-Heptose-6-Epimerase (Rfad) And Heptosyltransferase Ii (Rfaf) Biosynthesis Genes From Nontypeable Haemophilus Influenzae 2019, W A. Nichols, B W. Gibson, William Melaugh, N G. Lee, M Sunshine, M A. Apicella

Chemistry Faculty Publications

Haemophilus influenzae is an important human pathogen. The lipooligosaccharide (LOS) of H. influenzae has been implicated as a virulence determinant. To better understand the assembly of LOS in nontypeable H. influenzae (NtHi), we have cloned and characterized the rfaD and rfaF genes of NtHi 2019, which encode the ADP-L-glycero-D-manno-heptose-6-epimerase and heptosyltransferase II enzymes, respectively. This cloning was accomplished by the complementation of Salmonella typhimurium lipopolysaccharide (LPS) biosynthesis gene mutants. These deep rough mutants are novobiocin susceptible until complemented with the appropriate gene. In this manner, we are able to use novobiocin resistance to select for specific NtHi LOS inner core …

Characterization Of A Transposon Tn916-Generated Mutant Of Haemophilus Ducreyi 35000 Defective In Lipooligosaccharide Biosynthesis, B W. Gibson, A A. Campagnari, William Melaugh, M A. Apicella, S Grass, Jing Wang, Katherine L. Palmer, R S. Munson

Chemistry Faculty Publications

To define the role of the surface lipooligosaccharide (LOS) of Haemophilus ducreyi in the pathogenesis of chancroid, Tn916 mutants of H. ducreyi 35000 defective in expression of the murine monoclonal antibody (MAb) 3F11 epitope on H. ducreyi LOS were identified by immunologic screening. One mutant, designated 1381, has an LOS which lacks the MAb 3F11 epitope and migrates with an increased mobility on sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The gene disrupted by the Tn916 element in strain 1381 was identified by cloning the sequences flanking the Tn916 element. The sequences were then used to probe a lambda DASHII genomic library. …

Simulation Of Living Processes Utilizing Concurrency And Object-Oriented Programming, Aaron Ziegler

Honors Theses, 1963-2015

What does it mean to be alive? Is it possible to create artificial life-forms that are truly alive? Can a computer program be alive? To answer these questions, I first explore the history of artificial life, beginning with John von Neumann, who designed algorithms possessing lifelike capabilities, and moving on to other famous attempts, such as Horton Conway's 'Game of Life', and Thomas Ray's remarkable 'Tierra' project.

Also included is a discussion on the merits of Object-Oriented programming for simulating, and ultimately synthesizing life on a computer. concurrency is defined, and its value for stimulating and synthesizing life is made …

Late Holocene Eolian Activity In The Mineralogically Mature Nebraska Sand Hills, Daniel R. Muhs, Thomas W. Stafford Jr., James B. Swinehart, Scott D. Cowherd, Shannon A. Mahan, Charles A. Bush, Richard F. Madole, Paula B. Maat

School of Natural Resources: Faculty Publications

The age of sand dunes in the Nebraska Sand Hills has been controversial, with some investigators suggesting a full glacial age and others suggesting that they were last active in the late Holocene. New accelerator mass spectrometry radiocarbon ages of unaltered bison bones and organic rich sediments suggest that eolian sand deposition occurred at least twice in the past 3000 ^I4C yr B.P. in three widely separated localities and as many as three times in the past 800 ¹⁴C yr at three other localities. These late Holocene episodes of eolian activity are probably the result of droughts more …

Ecological Water Treatment System For Removal Of Phosphorus And Nitrogen From Polluted Water, Ray W. Drenner, Donald J. Day, Stacy J. Basham, J. Durward Smith, Susan I. Jensen

School of Natural Resources: Faculty Publications

We propose that phosphorus and nitrogen can be removed from polluted water using an ecological water treatment system consisting of periphyton and fish. In the proposed system, polluted water flows through a series of vessels, and the nutrients are taken up by periphyton growing on porous screens. Algal-grazing fish feed on the periphyton and either assimilate or egest the nutrients in mucus-bound feces that settle from the water into a sediment trap. Both the fish and their feces can be harvested as nutrient sinks. In this study we examined the effects of an algal-grazing cichlid (Tilapia mossambica) and …

Comparison Of Source Rock Geochemistry Of Selected Rocks From The Schei Point Group And Ringnes Formation, Sverdrup Basin, Arctic Canada, P. K. Mukhopadhyay, F. Goodarzi, Michael A. Kruge, M. H. Alimi

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

Organic-rich from the Schei Point group (middle to late Triassic in age) and the Ringnes formation (late Jurassic) from the Sverdrup basin of the Canadian arctic archipelago have been geochemically evaluated for source rock characterization. Most samples from the Schei Point group are organic-rich (> 2% TOC) and are considered as immature to mature oil-prone source rocks [kerogen types I, I-II (IIA) and II (IIA)]. These kerogen types contain abundant AOM1, AOM2 and alginite (Tasmanales, Nostocopsis, Leiosphaeridia, acritarch and dinoflagellate) with variable amounts of vitrinite, inertinite and exinite. Samples from the Ringnes formation contain dominant vitrinite and inertinite …

Using Graphing Calculators To Integrate Mathematics And Science, J. Garofalo, F. Pullano

Journal of Mathematics and Science: Collaborative Explorations

The computational, graphing, statistical and programming capabilities of today’s graphing calculators make it possible for teachers and students to explore aspects of functions and investigate real-world situations in ways that were previously inaccessible because of computational constraints. Many of the features of graphing calculators can be used to integrate topics from mathematics and science. Here we provide a few illustrations of activities that use the graphing, parametric graphing, regression, and recursion features of graphing calculators to study mathematics in science contexts.

Effect Of Room Arrangement And Blood Sample Collection Sequence On Serum Thyroid Hormone And Cortisol Concentrations In Cynomolgus Macaques (Macacafascicularis), Bryan L. Flow, John T. Jaques

Research Methodology and Laboratory Animals Collection

We evaluated the relationship, in cynomolgus macaques (Macacafascicularis), between rank for order of blood collection with serum concentrations of 3,5,3'-triiodothyronine (T3), thyroxine (T4), free thyroxine (FT4), and serum cortisol. These relationships were determined for males and females that were housed in two room arrangements. For both room arrangements, males and females were housed separately. For room arrangement 1, macaques were housed on both sides of the animal holding room. The sides of the animal holding room were designated as side A or side B. Blood was initially collected from animals on side A, then from animals on side B. Animals …
